Charizard
Lonely Nature
Item: Leftovers
Flamethrower
EQ
Aerial Ace
Sword Dance/Dragon Dance
Never use 10% increasing items if you can get better and never two attacks of the same type on the same Pokémon. And even with a defence boosting nature, Charizard’s defence will remain around average.

Milotic (You misspelled the name of your Pokémon, now you’ll never be a Pokémon Master!)
Bold Nature
Item: Leftovers
Surf
Toxic
Recover
Ice-Beam

Venasaur
Calm Nature
Item: Leftovers
Synthesis
Razor Leaf
Leech Seed
Sleep Powder
Always have Leech Seed and Sleep Powder on your Venusaur. EQ is only good when having an Adamant Nature and Curse of Sword Dance. But don’t ask me how a beast such as Venusaur can perform any kind of dance.
